SPECIFICATION forming part of Letters Patent Nb. 645,843, dated March 20, 1906.

Application filed October 23,1897. Serial No- 656j200. (N0 model.)

To all whom it mqtyooizoerfi:

Be it known that I, JOHN S. WORTH, a citizen of the United States, and a resident of Coatesville, Pennsylvania, have invented certain Improvements in Flanging-Machines, of which the following is a specification.

My invention relates to certain improve-- ments in machines for flanging metal plates; and the object of my invention is to so construct the machine that the operating parts can be adjusted so as to accommodate plates of different diameters and thicknesses and to regulate the bend of the flange as well as to center the plates on the machine, as fully described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a side view of my improved flanging machine. Fig. 2 is a plan View, partlyin section. Fig. 3 isa plan view, partly in section, of a portion of the machine drawn to an enlarged scale. Fig. 4 is a section on the line 4 4, Fig. 3. Fig. 5 is a transverse section on the line 5 5, Fig. 3. Fig. 6 is a sectional plan viewdirectly below the floor-level, illustrating the means for centering a plate on the machine. Fig. 7 is a side view of one of the centering-arms shown in Fig. 6. Fig. 8 is an end view of Fig. 7. Fig. 9 is a plan view on the line 9 9, Fig. 3, drawn to an enlarged scale and showing the roller-bearings for the anvil-roller. Figs. 10, 11, 12, and 13 are diagram views showing difier'ent methods of making the flange, and Fig. 14. is an enlarged view of a detail shown in Fig. 4.

A is the base of a flanging-machine, made in the present instance of two I-beams sup ported on suitable foundations.

Bis the centerbearin g, in which is mounted a vertical shaft B, carrying the head B upon which the plate to be flanged is placed.

A are uprights supporting the overhead framework A which carriesthe cylinder 0, having the piston-rod O, to which is attached the clamp C for clamping the plate onto the head 13*.

The shaft 13 isdriven in the present instance by means of a bevel-gear and pinion b b from a driving-shaft B but it will be understood that any form of driving mechanism may be used without departing from the main features of the invention.

.Adapted to slide upon the frame A is a carriage D, having two segmental guides 01-, forming quadrants, in which isguided the carrier E for the bending-roller e. Adapted to this carrier F. is a slidinghead E, having journal-f bearings for the bending-roller e, Fig. at. This head E is adjusted in the present instance by means of three set-screws e e 6 and these screws are geared together by Wheels 6 The center screw c has a thread cut in a direction opposite to the threads on the two side screws e so thaton turning the central shaft e in one direction by means of a hand-wheel, as shown by dotted lines in Fig. 4, the head will be moved away from the work, but by reversing the motion it will be moved toward the work. By this means the roller can be regulated to accommodate different thicknesses of metal and to flange the head over formers or rollers of different radii, so that the radius of curvature of the bend of the flange can be varied to any desired amount.

As shown in Figs. 4 and 14, the shaft c has a collar 6 between which and the carrier E is a spring 6 which tends to draw the head E into the carrier and to bind against the side screws 6 preventing chattering due to lost motion. The screws 6 c are adapted to headed nuts in the head E, as shown.

The carrier has a segmental rack f, which meshes with a pinion f on a transverse shaft F. This shaft has a pinion f which meshes with a vertically-arranged rack f attached to the piston-rod F of the cylinder F mounted upon the carriage D. On operating the valves to allow for the flow of fluid into the cylinder the rack can be moved up or down, and consequently this motion will be imparted to the carrier through the pinions and its segmental rack, so that it will turn in the segment of a circle, and the roller 6, carried thereby, will form a flange of the proper radii on the plate inserted between the head B and the clamp.

In order to limit the downward movement of the carrier, I provide an adjustable stop G, Fig. 5, against which strikes the end of the rack f This stop is in the form of a screw splined throughout its entire length and held from turning by means of a key g, resting in this spline and secured to the bracket D, depending from the carriage D. Adapted to the threads of the screw is a nut g, having bevel-teeth which mesh with the bevel-pinion 9 on the hand-shaft 9 provided with a hand-wheel 9 so that on turning this handwheel the stop G can be raised or lowered to limit the movement of the rack f and consequently the movement of the carrier E, in its segmental guides.

In order to move the carriage toward and from the work, I provide two screw-shaftsH H, which pass through screw-threaded lugs D on the carriage. These screw-shafts H have gear-teeth h at their extreme ends,which mesh with the intermediate wheel h, and one of the shaftsI-I has a hand-wheel k by which it is turned, so that both shafts turn in unison, being geared together by the intermediate wheel h. 011 turning the hand-wheel in one direction the carriage is moved toward the work, and on reversing the movement it is withdrawn from the work. The shaft on which the wheel h is mounted may be provided with belt-pulleys, as shown by dotted lines in Fig. 3, for driving the screw-shafts H by power.

I is a saddle mounted on the lower frame A of the machine, and this saddle carries-the roller-anvil I, Fig. 11, which isused when the plate to be flanged is of a greater diameter than the head B This saddle can be moved toward and from the center of the machine by means of two screw-shafts J J,'adapted to screw-threaded lugs 71 i on the saddle I, and these shafts extend to one end of the machine and are geared together through the medium of bevel-wheelsjj and a cross-shaft J so as to receive a hand-wheel, as shown by dotted lines in Fig. 3, so that the screw-shafts can be turned in unison to move the saddle.

In order to operate the carriage D and the saddle I in unison, I mount on one of the shafts II a gear-wheel 7t and on one of the shafts J a gear-wheel 7a, and I gear these two wheels together by a sliding intermediate wheel so that when it is wished to operate the carriage D and the saddle I in unison the intermediate pinion is thrown into gear with the two gear-wheels 7t 7t, and by turning the hand-wheel 71 all the screw-shafts will be op-. erated and the carriage and saddle will be moved together; but by sliding the wheel k out of engagement with the wheels 7c 70 the two sets of shafts can be moved independently.

In order that the roller-anvil I shall work freely in its bearing in the saddle I, I form the spindle i, which extends down into the saddle and rests upon the stop 1, and it is supported at the sides by rollers 2' arranged between the bearing and the stem, as shown in Fig. 9, thus considerably reducing the friction and allowing it to freely revolve as the plate is rotated.

In order to center the plate in the machine, I provide three or more arms-four in the present instance, as shown in Figs. 2 and 6. The arms L extend up above the surface of The end of this cross-shaft is squared,-

the clamp O is made in two parts 0 c.

, the head 13 and are preferably provided with vertically-arranged rollers Z at their extreme ends and are mounted upon carriages L, adapted to slide upon guideways M, which radiate from the center of the machine and are secured to the base-frame A of the machine at their inner ends and to stands M at their outer ends.

.On the under side of the carriages L" are racks l, which mesh with pinions m on shafts These shafts are geared in pairs by bevelwheels 02, so that they will turn in unison, and each pair is geared to a driving-shaft P by bevelwheels n and p. a t.

The driving-shaft P has a pinion p, which meshes with a rack P, attached to the piston l? of a cylinder P so that when fluid under pressure is allowed to flow into one or the other end of the cylinder the rack will be moved in one direction or the other and will consequently turn the series of shafts and move the carriages and their arms toward or from the center of the flanging-machine.

To center a plate on the head B of the machine, all that is necessary is to operate the valves so that the arms will travel in unison toward the center of the machine, and they will thus center the plate, so that it can be properly flanged, after which the plate is held firmly onto the head B by the clamp 0 Fig. 10 illustrates a plan of flanging a plate where the flange is turned down directly onto the edges of the head 13 by the roller e.

Fig. 11 shows the method of turning down a flange of a plate of larger diameter by using the saddle I and its roller-anvil I, which is adjusted so as to be beyond the head B The carriage in this instance is moved backward, so that the roller 2 will turn down the flange over the roller-anvil.

It will be noticed in Figs. 10 and 11 that These parts are secured together in any suitable manner, preferably by bolts. They form then simply a flat clamp fora flat plate; but by detaching the two and securing the part c to the head B as shown in Fig. 12, a previouslydished plate can be clamped between the two parts, or the plate may be dished by the clamping operation.

The edges of the plate can be then flanged by the roller 6, as in Fig. 12, so as to produce a dished flanged head.

When the dished plate is much larger than the part c, as shown in Fig. 13, I may elevate the lower part c by inserting washers or plates 0 between the part c and the head 13 so as to adjust the plate in respect to the anvilroller 1, which is moved out to flange the plate at the proper point. It will be readily seen that I can by this method reduce the cost of special clamps or heads for this type of flangingmachine and can adjust the parts very quickly to flange different-sized plates. The roller-anvil I can pass under the edge of the former 0' when necessary, so that the full effect of the clamp is obtained and at the same time utilizing the anvil-roller. In some cases this convex plate may form part of the head B but I prefer to make it detachable, so that I can use the same head for flanging either flat or dished plates.
